To all wlw/mJ it may concern.' l l Be it known that I, CHRrsTorHER O. COLE,

a citizen of Athe United States of America.

and a resident of the cityA of Bellingham, in4 the county of Whatcom and State of Washington, have invented certain .new andl useful Improvements in Hauling -Apparatusl of which the'following isa specification.

My invention has particular reference to; apparatus of the above. type and has for one; .of tsobjects the provision of means through the vmedium of which power for hauling is applied to the line at a plurality of points."

A-i`urther object is to provide means by which one haulinr device is automatically.

Other objects will be set forth as de-.H scription 'progresses and those features' of construction, arrangements and combina'- tions of parts, in which my invention re' sides, succinctly defined. in my annexed claims Referring to the laccompalaying'drawingev illustrating my invention in such form4 as now preferred by me, and wherein like nu.-

Spring 13, is interposed between one of these lugs 1 2 at the rear sidethereof, and theadjaeent spoke 1l', and hasits tension regulatedyas. by an vadjusting screwA 14 having threaded engagemen-t in said spoke. V

Reference numeral ...1i-indicates an este` rior friction clutch 'cone fixed; tol the outer face of elementv 12 and adapted for reeepL tion of aninteriolf friction cone 18-provid'ed` en the adjacent end portion .of drinn 1,

disclosed a well knowntyp@ of mechanism comprising; a screw 19. mounted in a nut part obraeket 2()v and; engaged with a thrust pin 21, slidably mounted. in a longitudinal. opening ofl shaft; 16 and bearing against a gib 22 secured to a slide collar on shaft 16 and slidably fitting in a suitable transverse slot of the shaft, as shown in Figs. 1 and 4 to be brought, by proper ma- 5 nipulation of screw 19, to bear against the hub of drum l. A spring 23 returns drum 1 to open the clutch upon proper manipulav `tion of screw 19.

Reference numeral 24 indicates the driver '10 for drum 1, the same being provided with a gear 'wheel 25 meshing with a loose pinion 26, mounted on a transverse shaft 27 of frame 4 and having releasable connection with said shaft by a suitable clutch 28, pref- 'T'f ft'ably of the friction type. Shaft 27 is also vprovided With a fast pinion 29, which latter is in mesh With gear wheel 11. Reference numeral 30 indicates a second driver, this being rotatably supported and provided '20 on its shaft 34 with a gear 33 from Which power is transmitted vto drums 2 and 3, by a link chain 31 to a gear: 32, fixed to the shaft of pinion 7. Drivers 24 and 30, in ythis the preferred embodiment of my invention, constitute outer and inner elements respectivel of a motor 35 of a known type, wherein t e outer element, carrying the usualfield magnets, and the inner element or a rmature are both free for rotation, the said V outer element having its casing provided with the gear wheel 25 and with hub extensions 24', the latter being journaled on the armature shaft 34. I l i Reference numeral 37 indicates -a disk,

l of insulating material, of a suitable brake 36 for shaft 34, the same being xed to said shaft and. encircled by a brake band 37, Whose free end portions are connected with an operating lever 38, fulcrumed at 38 on .40 frame 4. Operating lever 38 is connected -With the operators .lever 42. Solenoid 39v is connected in shunt to thev motor circuit lead wires 44, connected with any suit-able source of electrical energy, through a rheostatic controller 43 of'any well known type. Controller 43 is fixed, as by brackets 45, to

' one spoke 11 and connected by wires 46 with conductor rings 47 and 48 respectively mounted in sui'tablefinsulating material, as shown, in the side face of drive gear 11.

Reference numeral 48 indicates resilient fingers each engaging a respective conductor ring 47, 48. These fingers 48 are mounted on a suitable stand 49 of framey 4 and connected by wires 50 with respective lead wires 44, and in one of these wires 50 solenoid therebyl maintain the line taut and ready .being journaled on shaft 16 and being free is included, as more clearly shown Lin-li i s. 2 and G. Controller 43 is provided on its rotary switch arm with 'a pinion 51 which is engaged by a rack 52 fixed. to an adjacent lug 12 of driven element 12.-

In operation, upon closing of the motor circuit, as by a switchl 53, of any lwell known or desired type, a portion of the current is shunted through controller 43 and solenoid 39, thereby applying brake band 37 to cause a' resistance to the rotation ofv armature shaft 34, while the remainder of the current passes to the motor through the usual brushes 54 and rotates the eld .magnets or outer element 24 around armature 3Q. Move- 80 ment of outer. motor element 24 is transmitted through gear wheel 25 and'pinions 26 and 29 tc gear wheel 11, which latter is connected through thei intermediacy of spring 13, driven member 12 and clutch parts 17 and' 18 with drum 1, as hereinbefore y set forth, and drum 1 is vthereby driven to wind cable 15 primarily to take up the slack Y therein. As the pull of the'load on cable. V15 overcomes thetension of spring 13, gear wheel 11 advances with respect to member A, 12 until the lugs 12 are in engagement with l theadjacent spokes 11. During such relative movement of gear 'wheel 11, rack 52 opcrates controllery l43 to 1 gradually include more resistance inthe shunt path' provided for the current and to finally open such path, thereby releasing the brake, so that' the desired power can qbe transmitted to drums'2 and' 3 as the'load is picked up. Should the load jump or skid, as on a down grade, Winding drum 1 .Will'race with line` 15, spinning-the haul drums on their shafts, Y

clutches 8 opening to permit of this, and

for lthe hauldrums 2 and 3 to pick up the load again. Simultaneously with the racing of drum 1, spring 13-for'ces driven element 11 forwardly and thereby operates controller 43 toapply brake 36 to keep the niotor armature 30 from speeding. Incon- .junction with drum 1, I preferably provide a line Winder 55 comprising spaced vertical armsreceivingtherebetween line 15 and tixedfto a slide 56, having a follower 57 for alternative engagement in the right and left hand grooves of a screw58 to be thereby reciprocated lengthwise of fdrum 1 l upon rotary movement of screw 58. Screw 58 is suitably -journaled on frame4 and provided on one end portion With a gear wheel 59 meshing with a pinion 60 on shaft 27.

Reference numeral 61 indicates a winding drum for the haul back -line 62, .said drum to be shifted 'lengthwise thereon by 'screw 63 to b ring its friction cone 64 into engagement with the exterior friction'cone 65 ofgear wheel 11, against the action -of the` clutch opening spring 66. '.In connection 130 incense With drums l 'and 6l, I provide brakes-67 and 68 respectively whereby the lines can' ,A flange eXtensions 70, of the drums, as clearly shovvn. in winding line 62, .on drum 61, drums 4l, 2, and 3 are released to turn on their shafts, and brake 36 applied by the manually operative lever 42 to hold motor element 30.

While I have herein disclosed a construction Which will carry out the various functions assigned thereto, various changes can be made with respect to the structural parts Without depart-ing from the spirit -ot' my invention as defined in my Aannexed claims. Further, While l have herein referred to the mechanism as intended for hauling, it is .to be understood that my invention is equally Well adaptable for hoisting.
